Let's divide 64291256 by 851
Our goal is to divide 64291256 by 851.

Step 1:
When dividing 6 by 851, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 851

On to step 2:
851 can be fit into 64 0 times, resulting in a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 851

Advancing to step 3:
If we divide 642 by 851, we get 0 and a remainder of 642.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 642, we get 642.
Grab the next digit (9) from the dividend, add it to 642, then carry on: 6429 / 851

Step 4:
If we divide 6429 by 851, we get 7 and a remainder of 472.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 5957 from 6429 and we're left with 472.
Bring next digit (1) of the dividend behind the 472 and repeat the process: 4721 / 851

Advancing to step 5:
851 goes into 4721 5 times with a remainder of 466.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
The remainder is 466 after subtracting 4255 from 4721.
Include the next digit (2) from the dividend after 466, then repeat: 4662 / 851

On to step 6:
The number 851 fits into 4662 5 times, leaving a remainder of 407.
Record the quotient 5 as the next digit in the result. 
Result so far: 755.0
If we subtract 4255 from 4662, we get 407.
Include the next digit (5) from the dividend after 407, then repeat: 4075 / 851

Let's proceed to step 7:
851 goes into 4075 4 times with a remainder of 671.
Write down 4 as next digit of the result. 
Result so far: 7554.0
Subtracting 3404 from 4075 leaves us with 671.
Take the next digit (6) from the dividend and append it to 671, then repeat: 6716 / 851

Moving on to step 8:
851 can be fit into 6716 7 times, resulting in a remainder of 759.
The next digit of our result is 7. 
Result so far: 75547.0
If we take 5957 away from 6716, we end up with 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Let's proceed to step 9:
When dividing 7590 by 851, we get 8 with a remainder of 782.
The next digit of our result is 8. 
Result so far: 75547.8
If we subtract 6808 from 7590, we get 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Going ahead to step 10:
If we divide 7820 by 851, we get 9 and a remainder of 161.
The next digit of our result is 9. 
Result so far: 75547.89
Subtract 7659 from 7820 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 11:
851 goes into 1610 1 times with a remainder of 759.
Put 1 as the next digit of the answer. 
Result so far: 75547.891
Subtract 851 from 1610 to get 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

Going ahead to step 12:
851 can be fit into 7590 8 times, resulting in a remainder of 782.
The number 8 becomes the next digit in our result. 
Result so far: 75547.8918
Subtracting 6808 from 7590 leaves us with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Advancing to step 13:
7820 divided by 851 is 9 with a remainder of 161.
Use 9 as the next digit of our solution. 
Result so far: 75547.89189
Subtracting 7659 from 7820 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Moving on to step 14:
When dividing 1610 by 851, we get 1 with a remainder of 759.
Record the quotient 1 as the next digit in the result. 
Result so far: 75547.891891
If we subtract 851 from 1610, we get 759.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7590, and continue the process.

On to step 15:
The number 851 fits into 7590 8 times, leaving a remainder of 782.
Use 8 as the next digit of our solution. 
Result so far: 75547.8918918
Subtracting 6808 from 7590 leaves us with 782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7820, and continue the process.

Going ahead to step 16:
851 goes into 7820 9 times with a remainder of 161.
Record the quotient 9 as the next digit in the result. 
Result so far: 75547.89189189
Subtract 7659 from 7820 to get 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Our division results in 75547.89189189 with a remaining 1.61e-07.
